Winter Sky and Flocked Trees

Each of these photos feature Stratus clouds and trees decorated with newly fallen snow. Stratus are often featureless clouds with smooth bases that form during an invasion of colder air. These stratus formed near the top of a moist layer of air aloft in a region of upward motion. The upward motion developed in a northwesterly flow of air with broad cyclonic circulation over the Upper Midwest after a snowstorm.
